I can't forget seeing my younger brother who went to the army on vacation to com back home without telling anyone in his family as a surprise. Because it was the most recent thing I experienced and I was so surprised that I couldn't forget it. My younger brother went on vacation without telling me to surprise our family, but when he came back home, I was so surprised that I collapsed on the spot and cried a lot. Now I remember that day with a smile, but I was so shocked and it was the first time I experienced that, so it was more memorable.
